I bought a gameseeker three years ago for my 7mm mag, clear and it came stock with the ballistic plex. Really bright, but the eye relief was attrocious when crancked up to 9. Got smacked on the head and then the wife bought me a ziess conquest.
I mounted the pentax on my sisters 270 (Mossberg ATR( Darn good for 250 bucks) and it is just about perfect for that little rifle. It seems to work great for her. Good quality for 100 bucks. EJ
